Why did the computer screen turn black?
If the computer screen turned black, the following ideas could be used to solve the problem: ** 1. Black screen after computer is turned on ** 1. ** Check the power supply of the host ** - Check whether the power strip is energized, whether the power strip switch is pressed, and whether the power plug of the host is loose to ensure that the host is energized normally. 2. ** Check the host's start-up status ** - ** Host has been started ** - After pressing the power switch, under normal circumstances, you could see the green or blue indicator light on the host panel (unless the indicator light on the case panel was damaged), and you could also hear the sound of the fan rotating in the case. If the host has a small speaker, a beep will be heard after the normal self-test, and the screen should light up at this time. - ** Host not started ** - ** Host self-test not completed ** - If you confirm that the host computer is powered on but you don't hear a beep, and the indicator light doesn't light up even when you press the keyboard's CapsLock key, it may be due to poor memory oxygen contact (especially when the computer suddenly can't start). If the host has a small speaker, the memory self-test may hear an "beep" alarm and other error prompts. The solution was to open the case, pull out the memory stick, and reinsert it with an eraser. This could solve 90% of such black screen failures. - ** Host self-test completed ** - If the keyboard's case-size indicator light can be switched with the keys, but the monitor does not light up, it is useless to replace the monitor. It may be a problem with the graphics card. First, check whether the host has a standalone graphics card or an integrated graphics card, and whether the signal cable is plugged into the integrated graphics card. If the signal cable is plugged in correctly, you can pull out the standalone graphics card, plug the signal cable into the integrated graphics card output interface (provided that the CPU has a nuclear display), and turn on the computer to see if the display is lit. Many times, poor contact with the goldfinger of a standalone graphics card would cause this problem. The solution was to pull out the graphics card and wipe the goldfinger with an eraser. 3. ** Check the power supply of the monitor ** - If you hear the beep but the screen doesn't light up, press the monitor power switch to see if the indicator light is on. If the indicator light is not on, check if the monitor power plug on the power strip is unplugged; if it is an external power supply, try to replace it. 4. ** Check the display signal cable ** - If the indicator light of the monitor is on and the image on the screen flashes but no blue desktop appears, check whether the signal wire of the monitor is plugged in properly. Even if it is plugged in properly, unplug it and plug it in again. The plug connecting the host and the monitor must be plugged in again to prevent poor oxygen contact. 5. ** Check the display signal source selection ** - If there was no problem with the signal line, call out the display's OSD menu to check the signal source settings. If the settings were inconsistent with the signal line, reset it. If the signal setting and the host were fine, the monitor might be damaged. You can replace it with a normal monitor for testing. ** 2. The computer screen turns black during use ** 1. ** Brightness problem ** - Use the shortcut keys to adjust the brightness. There are usually special shortcut keys on the computer keyboard (such as the F2 key or the key with the sun symbol) to increase the brightness of the screen. If the brightness is adjusted to the lowest and the screen turns black, you can increase the brightness through the shortcut key. 2. ** System or Driver Problem ** - Trying to enter safe mode. In the Windows system, restart the computer, press the F8 key when the system starts up until the boot options interface appears, select "safe mode" and enter; in the MacOS system, restart the computer, press the Shift key when starting up until the login interface appears. After entering safe mode, you can try to adjust the screen brightness again. 3. ** Other situations ** - Reboot the computer, press the power button to completely shut it down and then restart it again to see if the screen returned to normal. - Check if there are any updates available in the system and proceed with the update. In the Windows system, find and install system updates through the "updates and security" option in the "settings" application; in the MacOS system, find and install system updates through the "software updates" in the "system preferences". - If you suspect that it's a hardware problem, you can connect it to an external monitor to see if it's working properly. In addition, if the computer power indicator lights up, the fan turns, the black screen does not show and the keyboard light does not light up, it may be that the memory stick is loose or there is too much dust. You can wipe the memory stick and re-install it. If the computer shows a black screen after starting up, and the power light flashes, it may be the host power failure. You can open the case and re-install the power supply and the connection cable of the main board. If it still cannot start, it may be that the power supply is broken. Change the power supply. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The screen went black when I was reading a novel
The black screen could be caused by a variety of reasons. Here are some possible solutions: - ** In terms of hardware failure ** - ** Monitor or screen problem **: If the screen of an electronic device (such as a mobile phone, tablet, or e-book reader) is damaged, professional repair may be required. For example, the cable on the screen was loose or the screen itself was physically damaged. - ** Video Card Failure (for computer equipment)**: A problem with the video card may also cause a black screen. For computers, you can try to plug in the graphics card again (if it is a standalone graphics card) to ensure that the graphics card is installed correctly and in good contact. - ** Loose memory stick (for computer equipment)**: Loose memory stick may also cause such problems. You can open the computer's main body case and plug the memory stick in and out again. - ** In terms of software conflicts ** - ** Driver incompatible **: If it is a computer or some device that requires a specific driver, it may be that the display driver corresponding to the novel reading software is incompatible with the system. You can try to update the driver to the latest version to solve the compatibility problem. - ** Operating system update failure or software conflict **: If there is an operating system update or new software installed recently (including the novel reading software itself or other related software), a conflict may occur. You can try uninstalling recently installed software or repair the operating system (such as using the system's own repair function or reinstalling the operating system, but be sure to back up important data before reinstalling the system). - ** Power supply problem ** - ** Loose power cord or power failure **: Check whether the power cord of the device is plugged in tightly. If it is a mobile device (such as a mobile phone or tablet), check whether the charger is connected to the device and the socket. If it is a computer, check the power cord of the monitor in addition to the power cord of the host. If the power supply itself fails, such as a damaged power charger (for mobile devices) or a damaged computer power supply, the power supply may need to be replaced. - ** Device settings (for some devices)** - ** Screen Brightness **: Check if the screen brightness has been adjusted to the lowest, which may cause a black screen. If you adjust the screen brightness appropriately, see if it can be restored to normal display. - ** Special function mode (such as the anti-accidental touch mode of the phone)**: Some devices may have special function modes. For example, if the phone is in the anti-accidental touch mode, a black screen may appear when reading a novel. You can turn off the relevant function mode to check. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
